The ''' character cannot be used in a path.
I am trying to import HTML files from a previous version of online help into a newer version, but am getting the following error:
"The filename is invalid. The ''' character cannot be used in a path."

I have checked filenames of all HTML topics but I could not see '' or any other special characters having been used. This is happening for all HTML files in the older release of the help, not just one. Used version 9 for creating the older version, and that's what I am using for the new version. Please advise.
If this error cannot be resolved, I'll have to manually copy the content from older topics into topics created in the new help.
